Материалы к фауне и экологии муравьев (Hymenoptera, Formicidae) юго-востока Украины

Abstract

44 species of Formicidae were registered in the territory of the South-Eastern Ukraine for 1969-1971. Ecological peculiarities of each species were determined and general and particular regularities were detected in distribution of ants within the limits of the south-eastern part of the steppe zone in the Ukrainian SSR. It is established that distribu¬tion of ants is affected by two main factors: peculiarity in the growth conditions of the forest stands within the steppe zone and character of ants' nesting. The problem is discussed on possibility to use Formicidiae as an additional factor when estimating ecological conditions of the forest-steppe plantations.
